Introduction (1) FLOODSTANDWhy FLOODSTAND ?

• missing data for validation of time-domain numerical tools for assessment of passenger ship survivabilityand

• a standard for a comprehensive measure of damaged ship stabilityaddressing the flooding risk- reflecting the stochastic nature of damaged ship stability in waves- based on first-principles modeling - reflecting foundering as a process (loss of flotation/stability)- considering risk-based decision making

1. Modelling of leaking and collapsing of non-watertight structures

2. Finding out pressure losses (discharge coefficients) in typical openings

3. Simplified modelling of complex compartments

4. Flooding detection and damage estimation

Numerical modeling and criteria for leaking and collapsing structures => Work completed

Responsible: MEC; Other Participants: CTO, NAPA, STX

- Focus on failure mechanisms for doors and structural components

- Numerical simulations; explicit FEM code

- Flow rate vs. water pressure

- Specific data obtained also on

-- the leakage pressure, i.e. when the structure

looses watertight integrity and-- the collapse pressure gets it to collapse.

- Computations will be validated with experiments

=> criteria for leakage and collapse of doors etc.

An example of FLOODSTAND results:

Based on this workrough guidelines for modelling leakage and collapse of various A- and B-class doors etc. for flooding simulations could be given

These guidelines will be further providedfor IMO's use.
